XDM is very accurate out of the box.
I am chuckling at the premise of this thread. Accuracy in a gun that has iron sights and a baseline of no more than 6 inches, probably half that. Sure, accuracy inside 25 feet. Some of the comments about ‘tack driving’, my eyes are rolling. Compare this to keeping a group within an inch at 200 or 300 yards. But I don’t mean to squelch the enthusiasm of pistol shooting folks. I shoot a lot of pistol as well, but inside of 50 yards, the emphasis is on speed. Accuracy means keeping the rounds inside the thoracic cavity or the head box. Don’t need a tack driver for that.
